, T 0 all whom it may concern:

Be it known that l. (11min Enron, n citizen of the United St ates, residing at lienoshn, in the county of lienoshn and State of a l cousin, have invented cert-21in new and useful Improvements in Milk (footers and floral of which. the following is a. specification.

The object of my invention is to produce an improved apparatus for aerating, deodorizing and cooling; Warm milk or creznn.

The accompanying drawing is a central sectional View of an apparatus embodying: my invention.

The embodiment herein shown of my invention essentially consists in a conical cooling surface 1. In this instance the szrid cooling surface is coinposodof tuhin arranged in a helical coil upon the outside or a shell or structure 2 which has the form ol :1 conic lrustuxn. The lower end of the helical coil is provided with an inlet 3, and the upper end Zontal so as-to term a shell down which the j milk may flow around the helix.

employed, and that if the turns of the helix were arranged close'enough together to prevent the passage of milk between said turns the structure 2 could he omitted.

A slightly rounded cover 7 is provided to lit over the upper end of the. structure 2 and preferably is made removable. Altncl'ied to said cover is a basin 8 in the lower portion of Whose sides are perforations 9 n opted to spread the milk evenly over said cover, whence it runs onto the turs ol the cooling coil.

and the surloce sufficiently chilled the worm milk is poured into the basin 8. As the mill; llows through the perforations 9 and onto the cover '7, it spreads out in a thin layer and runs onto the uppermost turn From here some of the the upper sideof the helical tube 5, and some of the milk will drio from one turn oi. the coil to the next. lfhen the milk has reached the lower turns of szrid coil it will have been thoroughly aerated and deodorizcd, and its temperature will have been the cooling medium.

As it is possible to vary the construction of the epparatus herein described Without departing from the spirit or" my invention, 1 do not Wish to he restricted or limited to the precise construction herein shown.
